Aj BUTTONHOLE GAUGE. I

Application med October` 28, 1924. serial No. 746,338.

To all who/inzit mayeoncem: iBe it Vknown that I, HARRY D. SIMMONS,citizen. of the United lStates ofAmerica, andifresident of Troy, in thekcounty of Rensselaer and State 1 of NewfYork, have invented new anduseful Improvements iny Buttonhole Gauges, of which the following isaspecification. .Y l

This linvention relates to devices `for positioningV collars Y (lorycuffs)- on button-hole makingy machines soA4 that the ybutton-holesareimade in the .correct placefor a given Heretofore it has beennecessary for large collar manufacturing establishments toemploy'skilled gauge ysetters who go from one button-hole makingvmachine to another adjusting them to accommodate collars of a stylediiferent from the style for` which they had previously'beenset.; Thesegauge setters measure the collars to determine the correct. position forthe button-hole and-y manipulatecertain. devices on the machineaocordingly before Vtheoperator can continue the-work. It will`beevident that in facto-- riesfemploying a large' number of suchmachines much time is lost in waiting forthe gauge setter, kthus addingconsiderably to the-.cost of production.

` Objects `of the invention are to' enable un-V skilled operators. topositionA soft 'collars properly with respect to the button-hole makingmechanism-.in a simple and convenient manner; to provide an attachmentfor button-hole making machines having adjustable positioning deviceswhich may be readily manipulated; and toprovide a new and improvedpositioning device having the features'of construction and arrangementhereinafter described.

For purposes of illustration the invention is shown in the .accompanyingdrawings in which- Figi`v is a top plan' view-of a device forpositioningcsoftcollars with respect to button-hole ymaking mechanism;

Fig.v 2 isa side edge view of the device showing the relative positionof the cutter and needle; Y I l I Y Fig. 3 is a section on theline 3 3.of

' A illustrated, a relatively thin, fiat metallicplate A is providedwith a plurality' of holes l for the reception of screws, bolts or othersuitable fastening devices for connecting theplate to the carriage ofa.. button-V hole kmaking machine,. such as used.:- in making.button-holes in collars. Asy usually constructed .the carriage of suchmachines is propelled. in accordance with the .outline of thebutton-hole desired, the travel being with` relation to a needle 2 which.stitches the outline ofthe button-hole and thereafter a cutter 3 isactuated to out the hole;r It will be evident that the collarsfmust becarefully positioned on the plate A or the button-holes. will beimproperly .positioned and as a result thev collars will be rendereduseless;

. In practice: the collars are laid ont flat. on the plate A, acollarbeing indicated at.

I), positioned over an Opening 4 of substanthe other plate serving `toposition the collar forI making Aa button-hole at the other end. In.accordance with the Vinvention these .stops are readily andconveniently adjust-able so that an unskilledcoperator can l v adjustthe machinefor various styles of cole larswith a minimum amount oftrouble and expenditure of time as will hereinafter bek described.

The stops for positioning the end of the.

collar B comprises a narrow plate or arm.

5 .which rests upon the upper surface of the plate A and is providedwith a finger 6 tixedthereto having an lupturned pro]ection 7 which isadapted to be engaged by the notch in the collar B formed between thewing or fold -and the collar band. Thus when the collar B is moved toengage the projection 7 after the manner described the band of thecollar is positioned with respect to the stitching and vcuttingmechanism oi the machine. rllie stop 7 is adjustable to vary theposition ot the button-hole crosswise oit thel collar band as well aslongitudinally thereof to accommodate collars of different styles andsizes.

For adjusting the position of the stop 7, the narrow plate 5 isadjustably connected to substantially L.shaped arm 9, which is formedwith a pair ot parallel, rectangular elongate slots 10 and 11, aprojection 12 on the under surface of the plate 5 being guided in theslot 10. A plate 13 is formed with a similar projection extending intothe slot 11 and is clamped to the arm 9 and plate 5 by screws 11i. Thusit will be observed that by loesening the screws 1a the plate 5 may beadjusted in one direction or the other to move the stop 7 crosswise withrespect to the plate A, thereby positioning the collar B, relative tothe longitudinal margins of its band and the stitching and cuttingmechanism.

The stop 7 is further adjustable at rightangles to the adjustment abovedescribed in order to adjust the position oit the collar longitudinally,with respect to the stitching` and cutting mechanism, thus accurately toposition the button hole lengthwise of the collar. Accordingly plates 15and 16 are clamped as by screws to the opposite faces of the arm 9 andproject over the plate A, a projection 17 on the upper face of the plate16 extending into an elongate guide slot 18 in the plateV A and a screw17 holding the projection 17 in the slot. The opposite end of the arci 9extends over the plate A, a plate 19 being secured as by screws to theplate A and having an elongate slot 20 through which extends a screw 21for fastening the arm to the plate 19. Thus by loosening the screws 17and 21 the arm 9 may be adjusted to change the position of the stop 7longitudinally with respect to the collar B.

To adjust the location ot the collar B angularly with respect to thecutting and stitching mechanism thus to vary the angular position of thebutton-hole relative to the longitudinal margins of the collar band, astop 8 in the form of an upwardly projecting pinis {ixed to a plate 22which is formed with an integral projection 28 extending into anelongate guide slot 24, a plate 25 on the under side ot the plateA beingclamped to the plate 22 as by screws 26. By loosening the screws 26 thestop 8 may be moved in one direction or the other so that when the stops7 and 8 are properly adjusted for a given style a collar may be readilypositioaed on the plate A against the stops accurately for making abutton-hole.

To enable unskilled operators to adjust the stops properly for differentstyles and sizes of collars the various adjustments are preferablylettered D, L and S; D indicatingl the adjustment of the stop 7crosswise with respect to the collar, L indicating the adjustment of thestop 7 longitudinally, and S indicating the adjustment of the stop 8 toregulate the angular position of the collar. Fired as by welding to theplate A adjacent om1 side of the slots 11, 18 and 24E are strips 2T, 28and 29 respectively of brass or other suitable material which areprovided with a number of serrations or teeth 30 the points of which aresubstantially flush with the sides of the slots.

ln practice each operator will be given a chart containing a list of thedifferent styles together with the proper adjustment for each style. Theadjustment may read D-etl, L-, S-S in which event the plate 5 will bemoved to a position four and onehalt teeth from the right end of theseries of teeth 30, the arm 9 will be moved to a position five teethfrom the upper end of the series of teeth in strip 28, and the stop 8will be moved to a position eight teeth from the right-hand end of theseries in strip 29. ln this manner eachoperator may adjust his machinewithout calling upon an expert gauge setter.-

Numerous changes in details of construction and arrangement may beeffected without departing from the spirit of the invention especiallyas defined by the appended claims and although the invention has beendescribed in connection with a button hole machine it is to beunderstood that it is not limited exclusively thereto but may beembodied in other machines requiring careful ad iustment and positioningof parts.
